Triptycene-derived p-dibromocalix[5]arene was synthesized by a fragment-coupling approach, whereas treatment of the triptycene-derived calix[5]arene containing three p-tert-butyl phenol groups and a 1,8-dimethoxytriptycene moiety with excess bromine

Inherently chiral biscalixarenes with hetero-cavities were synthesized by a covalent assembly of p-tertbutylcalix[5]arene with a 1,3-substituted calix[4]arene via 1,3-alkylation reaction and subsequent desymmetrization. The racemates were resolved by

We have designed and synthesized an inherently chiral calix[4]arene partial cone conformer, in which a crown-4 ether moiety, a carboxyl group, and a propyl group are convergent. Chemical resolution was achieved by use of (S)-BINOL as a chiral auxilia

For better understanding of the structure/property relationship of inherently chiral calixarenes in the 1,2-alternate conformation, we designed and synthesized an inherently chiral calix[4]crown-4 carboxylic acid 1,2-alternate conformer. Resolution o

An analytical tuning method was proposed for fuzzy PID controller used in Smith predictor in order to extend its application and improve its robustness. The fuzzy PID controller was expressed as a sliding mode control. Based on Lyapunov theory, Smith
